Multiple Choice

In acute decompensated heart failure, which therapy improves oxygenation and reduces work of breathing?

Noninvasive positive pressure ventilation (CPAP or BiPAP) directly improves oxygenation and reduces the work of breathing in acute decompensated heart failure with pulmonary edema. The positive airway pressure keeps alveoli open, improving gas exchange, and it assists inspiratory effort, lowering the work required by the respiratory muscles. Additionally, the intrathoracic pressure from the tech reduces preload and afterload, helping to lessen pulmonary edema and further improve breathing. While diuretics and other therapies help with fluid overload, they don’t produce as immediate a change in oxygenation and respiratory effort as noninvasive ventilation.
